10 best cnet thermostat

Product description

Ordinary thermostats only read the temperature in one room, but are supposed to deliver comfort in all rooms. Ecobee3 remote sensors deliver the right temperature in the rooms that matter most. Now homekit enabled. Ecobee3 sensors know which rooms are occupied to deliver the right temperature in the right places. And they know whether someone's home to help you save energy and money when you're away. Ecobee3 comes with 1 free remote sensor that measures temperature and occupancy. You can have up to 32 sensors. The more you add, the smarter your Ecobee3 becomes at delivering comfort where it matters and savings where it counts.

• Works with Alexa for voice control (Alexa device sold separately).
• Smart, really smart - intuitively understands when to turn on your heating or cooling equipment based on your home's unique energy profile, the weather outside, and thousands of other data points to make sure you're comfortable at all times
• Knows you have a life - senses whether anyone's home and which rooms are occupied, delivering comfort when you're at home and saving you energy and money when you're not

User questions & answers

Question:	My thermostat is only used for heating the house and only has 2 wires, a red and white. Can i still use this ecobee
Answer:	If you have a really old 2-wire system, one that does NOT have modern solid state controls, then Ecobee won't work right off the shelf, even with their 2-3 wire power conversion module. These heating plants predate the 1980s and use "dry contact" thermostats. You can make it work if you install a 24v isolation relay. Ecobee outlines the procedure on their web site, but it takes some basic electrical wiring knowledge. I'm not sure if you can use the 2-wire conversion module with an isolation relay - it should be possible somehow or other. If you have a third wire running to the thermostat (it's often there) then you should use it to run 24V to the Ecobee, and ignore the conversion module.
Question:	Is there a provision to bypass the 'auto off' motion sensor so that my dogs don't suffer from the heat when I'm out
Answer:	Yes- you can disable the Smart Home/Away feature under the "Sensors" section of the interface, so that the thermostat will follow only the schedule/preset temperatures. In my case, I disabled it because I wanted the opposite functionality (I didn't want the system turning on if I stopped at home for a hour over lunch). Note that the "Follow Me" feature is a separate setting (found in the Sensors section as well) that allows the system to track where you are in the house and attempt to heat/cool that part of the house closer to your desired setpoint.
Question:	Does the main thermostat have a sensor for the first floor? Or is the white sensor needed for that floor? Is the black hub a sensor
Answer:	Main thermostat and white (remote) includes a temperature sensor and a motion sensor. First, you don't have to use the remote sensor. Second, if you use the remote sensor, the main sensor will combine the input of both (main and remote) temperature sensors and based on the amount of time spent in each area using the motion sensor. If motion is detected more near the main and less near the remote (as a %), then the main temperature will weigh heavier than the remote. As well, you do not need to use remotes and can be assigned to work during selected schedules only. It's quite amazing, but I haven't used them on my system yet. I figured I would learn the rest of the system before I introduced them.
Question:	is this a different model than the ecobee3 that is slightly less expensive? Also if wifi is out can you control it fully manually
Answer:	Yes, this is a different model then the ecobee3 lite. The ecobee will still be able to function as a thermostat and talk to the sensors, if your wifi goes out. You can still manually control your heating and cooling at your ecobee without wifi.
Question:	Compatible with alexa? do i have to buy nexia bridge for it to work
Answer:	For the thermostat alone, no nexia bridge is needed.
Question:	Can you set Temperature limits on this thermostat
Answer:	Yes you can.
Question:	The connection key to setup wifi will not work so i am not able to connect it to wifi. anyone know the fix
Answer:	Must use your phone and the app.
Question:	Is this thermostat compatible with the xr624 connection
Answer:	Yes, it is compatible. The XR724 replaces XL624.

User questions & answers

Question:	Does this require a c wire? why does it need aaa batteries
Answer:	No need to have a Honeywell gateway for the Honeywell rth6580wf. You only need a wireless Internet modem dsl/broadband service phone line.
Question:	Will this work with the nest remote temperature sensors
Answer:	I found this information on another website (http://programmablethermostat.info/honeywell-rth6580wf-wi-fi-7-day-programmable-thermostat/)Real Time Clock:This thermostat does NOT have an internal battery. All program and installer set up functions are saved on to a chip and retained in case of a power outage. It does utilize a super capacitor for short term retention of the clock. If there is a lengthy power outage and if the RTH6580WF is connected to the internet, when power is restored it will automatically resynchronize with the internet time.
Question:	I have 4 wires, 1st wire is w/ 2nd y/3rd is g/4th is rh will this thermostat work with these wires
Answer:	If you have no Internet, this thermostat will simply operate as a non-WiFi enabled programmable thermostat (e.g., follow the schedule that you previously created) OR you use the buttons on it to adjust it manually. The only thing you lose with not having the Internet is the ability to use your phone to interact with it (e.g., change the settings and/or update the schedule). Just pretend like it is 1970 and adjust the thermostat like your parents did.
Question:	Does this work with the nest temperature sensor
Answer:	I did the following in a two-wire heat-only setup and it worked: 1) On the back panel of the new thermostat, remove the small jumper between the RC and R connectors. 2) Connect the outputs of a 24V AC transformer (I happened to use https://www.amazon.com/gp/product/B07DJ7RHS5?ref=ppx_pt2_dt_b_prod_image) to the RC and C connectors on the new thermostat back panel. It does not matter which of these two wires goes to RC and which goes to C. 3) Connect the wire that had gone to either RC or R on the old thermostat to the R connector on the new thermostat back panel. Connect the wire that had gone to W on the old thermostat to the W connector on the new thermostat back panel. 4) Plug in the transformer to a nearby 120 V outlet. Snap the body of the new thermostat onto its back panel. Continue with the instructions provided with the new thermostat.

User questions & answers

Question:	How to wire up voice thermostat with only 2 wires ,r and w
Answer:	In most cases, Nest thermostats can get enough power from your system’s heating and cooling wires. But in a small number of situations you may need to connect a common or C wire to deliver enough consistent power to your thermostat when your heating and cooling wires are not able to deliver the needed power for your Nest thermostat. Battery drain issues normally happen when the power from your heating and cooling system goes out. The 2 AAA alkaline batteries are used as a backup, or to supplement if your system can’t deliver enough power.
Question:	I don't have a 'C' wire... how difficult is to adapt the Ecobee using the included cable and how is it done
Answer:	No
Question:	If you have an echo (alexa) in the room already, is there a way to turn the alexa on the thermostat “off”? or turn off the microphone/listening
Answer:	I found an interactive video on my utility’s website (Commonwealth Edison) that ran through the wiring questions. It will tell you if your system is compatible with Nest thermostats.
Question:	Can the Mic and Alexa be turned off
Answer:	No. Sensors are not compatible.

And it’s simple to install yourself – just hang it on the wall or place it on a shelf.

[1] The Nest Temperature Sensor requires a 3rd generation Google Nest Learning Thermostat or a Google Nest Thermostat E. Identify your thermostat at nest.com/whichthermostat.

[2] Remote control and mobile notifications require working internet and Wi-Fi.

• Works with compatible Nest thermostats [1]; the sensor tells the thermostat what the temperature is in the room where it’s placed and the thermostat uses that reading to control when the system turns on or off to keep that room the temperature you like
• Put different temperature sensors in different rooms, like the baby’s room or living room
• Control your Nest sensor in the Nest app; set a schedule and choose which room to prioritize when [2]
• Compatible with the Nest Learning Thermostat and the Nest Thermostat E [1]
• The Nest Temperature Sensor is easy to set up; just hang it on the wall or place it on a shelf
• The Nest sensor runs on batteries so it works in most homes; batteries can last up to 2 years
• Add up to 6 sensors for each compatible Nest thermostat in your home

User questions & answers

Question:	I am buying a nest e. do i really need to buy this sensor
Answer:	You don't need this sensor to operate a nest thermostat. The best has a temperature sensor built in. It will take the room temperature where the nest is installed and regulates the AC based on that room. Some folks have the need to control an additional space during certain times of the day. Most common would be a bedroom during night time. With the extra sensor you can set up the AC to bring the temperature of the bedroom to a certain temperature regardless what the temperature is in the room the nest thermostat is in. So it's a comfort feature. You can try the next by itself and if you find that you want to change temperature control to your bedroom you can add it later.
Question:	Hi my home has 5 zones do i need just one nest? or do i need one in each zone? would the sensors be good enough
Answer:	If you are going to replace your thermostat with Nest thermostat, a one for one replacement for each thermostat. Now, if you have just one thermostat and five zones, then it implies that you are monitoring temperature and providing feedback to the thermostat for each zone. To put it simple one nest thermostat, plus sensors will give you the hability to keep one selected room at a temeprature desired. Just select the sensor you want to set as controlling. For more than one thermostat you will need the above set up multiple times. The Nest application is one the most user friendly apps I have ever used.
Question:	How long does the battery lasts before it needs replacing
Answer:	2 years and still haven't had to change batteries.
Question:	Will this work with Nest Thermostat Gen 2 with the latest software
Answer:	Hi! Nest temperature sensor require an installed 3rd Generation Nest Learning Thermostat or Nest Thermostat E. Not compatible with Nest 1st Generation or Nest 2d Generation thermostats. Hope this helps.

Product features

Keep your home and family comfortable.

Most homes aren’t the same temperature in every room. Maybe the baby’s room gets too cold or the living room is too warm. Or maybe your thermostat is in a room where you don’t spend much time. The Nest Temperature Sensor helps make sure a certain room is just the temperature you want it to be.

How does it work?

Your sensor will tell your Nest thermostat the temperature in the room where it’s placed. Your thermostat will use that reading, rather than its own built-in sensors, to control when the system turns on or off. You can schedule it to use different sensors at different times of the day.

Compatibility.

It works with the Nest Learning Thermostat (3rd gen) and the Nest Thermostat E.[1]

Battery powered.

Wireless and runs on batteries, so it works in most homes. The battery can last up to two years.

Comfort from room to room.

Put temperature sensors in different rooms. And choose which room to prioritize when.

Simple setup.

Just hang it on the wall or set it on a shelf. Then forget it’s even there.

Control in the Nest app.[2]

Set a schedule for your sensors or learn more about temperature readings in your home.

Where should I install it?

In most homes, it’s best to install your sensor in a room where you spend a lot of time, like a bedroom or living room. Place it near chest height for the most accurate temperature measurement. And make sure it’s within 50 feet of your thermostat so they can communicate.

User questions & answers

Question:	Do I need to have a Honeywell gateway? This is an additional piece of hardware used by some of the Honeywell thermostats (ex. Prestige
Answer:	This Thermostat truly Rocks!! - It has a screen lock as well as Security codes for front panel access. It also has security if you want to use WiFi to remotely access it. Setup is a breeze also. I HIGHLY recommend this thermostat. The NEST is an excellent choice as well.
Question:	Without battery backup, what happens in a power outage? Is there internal memory that keeps the settings and how long, and is thermostat still usable
Answer:	What's Google home?
Question:	What happens to the room temperature when the internet is down
Answer:	I have a 5 year old Lux Thermostat. When we bought a new Rheem this past summer, the technician pulled the batteries out of it saying they were not needed. End result, is every time we have a power outage, the thermostat looses it's programming. it losses it when we change back and forth from heat to cool also. I'd be wary of any advice about removing batteries unless you're sure that it does not affect the thermostat memory. i say this as the A/C is on and it's program is set on 72 degrees. i had it set on 75 and have not attempted to reprogram it since that would be just a temporary fix it resets down to 72 often not sure why.
Question:	How do I figure out if this will work with my wiring? I read that there might be issues with the electric wires (might be missing one COMMON wire
Answer:	I just went to Best Buy to play with the RTH9585WF and see what is the difference in the settings. Color options do seem to be slightly different. Both have 7 day programing (four settings per day) plus vacation etc. The literature says the 9585 automatically switches between cool/heat but in 9585 system (MODE) there is only "heat", "cool" and "off". So my guess is the automatic is not a setting you pick. 9560 offers the forth option of automatic and will show heat and cool adjustments on the home page setting on the panel. Other than that I do not see any difference. My guess is the 9585 has a newer chip set but honestly I have no idea. I called Honeywell and the tech could not even tell me the difference other than it's the second generation model. Both work with Alexa and other smart devices and smart hubs. I'm still thinking of returning the 9580 for the 9585 but if I have to switch between heat and cold that is a deal breaker and I kind of like seeing the date when I walk buy. My guess is in a few years Honeywell will over a unit to compete with the Ecobee with something like Alexa built into it. Frankly, I'd purchase the Ecobeen 4 but my wife of 35 years thought the Ecobeen being black and kind of large and the white mounting plate was ugly and after 35 years of marriage I felt like this decision was not worth the fight.

From across the room or across the country, your Sensi Wi-Fi thermostat makes it easy to remotely control and schedule your home comfort - Anytime. Anywhere.

User questions & answers

Question:	Can you program just the fan mode
Answer:	Hi there, this unit REQUIRES an internet connection, based on a WiFi (wireless) connection. Once the device establishes an internet connection to the Honeywell cloud (which is cool!) you can effectively control the thermoostat from anywhere you have an internet connection.... even your smartphone. Enjoy!
Question:	Is it smart enough to decide whether to run the heater or cooler to keep the temperature fixed
Answer:	The WiFi setup requires you to create an account on mytotalconnectcomfort.com. It’s not that hard. The biggest problem with this thermostat is the unreliable remote connectivity ever since Honeywell spun off their thermostat division 6 months ago. Now it’s frequent periods of time where the thermostat will not respond to remote commands. It’s maddening
Question:	What if i have a C wire
Answer:	When you put it on circulate, the fan comes on for about 10 minutes every 20 minutes or so. The owners manual says it runs about 35% of the time. I used this feature this Fall with the system off (no heat or a/c) just to circulate the air through my Filtrete filters.
Question:	Can you create a fan schedule? I’d like the fan to always run from 10pm until 6am
Answer:	These thermostats are not the same. Even the screen is different. The RTH9580 doesn't have the 3D look of the 9300 series.
